Ronald Hoffman, M.D. is an American physician, author, and broadcaster in the United States who hosts Health Talk, a syndicated radio talk show. He is the founder and director of the Hoffman Center in New York City, and is a practitioner of holistic medicine.

Born in southern California, Hoffman studied Medicine at the Albert Einstein College of Medicine and was trained in Internal Medicine at the Manhattan V.A. In 1985 he founded the Hoffman Center, which is a unique, first of its kind, medical practice that pioneered alternative medical care.

In 1987 Dr. Hoffman started Health Talk, a medical talk show which is broadcast throughout the United States and Canada. Dr. Hoffman urges his patients and listeners that the best diet is to exercise five days a week, for 75 minutes, and eating well balanced meals.

Dr. Hoffman is a firm believer in the healthy benefits of nutritional therapy (not just by eating the right meals, but by nutritional supplements) - he personally consumes around 15 different supplements per day. The supplements Dr. Hoffman appears to be most interested in are Vitamin D, Magnesium (particularly Magnesium Taurate) and Fish oil. On almost every show of his he mentions a new medical study that backs his arguments about the risks involved with mineral and/or vitamin deficiency. Deficiency, Hoffman argues, can cause symptoms of diminishing health such as scurvy, disorders of cell metabolism, tuberculosis, poor psychological health (such as depression), osteoporosis, tinnitus, various forms of cancer, senescence (premature), cardiovascular diseases, and much more.

Although Dr. Hoffman maintains a friendly atmosphere on his show, he occasionally uses his radio time to voice criticisms of certain medical “experts.” He is a critic of NBC News Chief Science and Health Correspondent Robert Bazell, who he accuses of sloppy, inaccurate medical journalism. On April 30, 2007 Bazell reported on what he perceives to be the “placebo effect” of supplemental therapy (particularly the supplements glucosamine and chondroitin for treating arthritis.)- this resulted in a fierce rebuttal from Hoffman on his broadcast that same night. (see below links for details.)Hoffman is also a vehement critic of author and former convicted felon Kevin Trudeau, who wrote the famous controversial book Natural Cures "They" Don't Want You To Know About. He considers him to be a swindler that is an embarrassment to the field of complementary medicine.

Dr. Hoffman moved to New York for college and has remained there ever since. He owns two homes, one in Manhattan, and one in the Hampton Bays.
